Vitamin K is ingested, stored by friendly bacteria found in our gastrointestinal tract till its needed. Bacteria releases it and is absorbed by small intestine and liver to help in coagulation and bone metabolism.
It works as a coenzyme during the conversion of inactive zymogens produced by the liver (clotting factors) to prothrombin. Vitamin K aids enzyme carboxylase in catalysing the carboxylation of glutamic residue reactions. Prothrombin is vitamin K-dependent clotting factor that activates into thrombin then fibrinogen. Without vitamin K there will be no blood clotting and will bleed to death.
brine flies prefer warm temperatures to breed in, more brine flies means more food for the brine shrimp, so brine shrimp will be able to breed more as there's more food. and vice versa- in colder temperatures there would be less breeding of the flies, meaning less food for shrimps. therefore less breeding of shrimps)
Classical conditioning or Pavlovian conditioning is conducted on living organisms to make them associate one or more actions to a given (often familiar) stimulus or stimuli. Ivan Pavlov, in his experiment, trained a dog to associate an action, salivating for food, with the sound of a metronome.
